Fail to upload challenge zip file

[hadibokaei]

Hello I am new to evalAI and I have reviewed its features. Thanks for the great platform. I have installed it on a server using docker and I want to access it through the valid IP. Everything is OK except uploading a challenge zip file to create a new challenge. When I upload the zip file the following error is appeared in the log:

I cant understand what the problem is. Any help is appreciated.

I have the same problem. The .zip file is correctly uploaded. It seems the uploaded file cannot be correctly decompressed. I am still finding a solution.
